Sept. 1, 2010 - Swedish market pulp producer Rottneros said that its Board has approved an investment of SEK 60 million for a new biological water treatment plant at its Vallvik Mill in Sweden.

The investment is part of a larger program to improve the evaporation plant and the recovery boiler at Vallvik.

Work on this stage of the project will be carried out during the planned maintenance shutdown at the mill in October 2010, Rottneros said.

The new water treatment plant will come on stream during the fall of 2011, when the company expects to implement the final stage of the investment program.

"The investment program that is going ahead at Vallvik Mill resolves long-standing discussions with various levels of the environmental agencies, at the same time as expanding the production of bioenergy at the mill and increasing production capacity by 20 percent to an annual figure of 242,000 tonnes", explains Ole Terland, President of Rottneros.
